Gerald L. O'Barr <globarr...@yahoo.com> comments:
I have not read all your reference. But let me
tell you a few things. SR is not a physical theory.
It is only a math theory. Thus, it is physically
impossible for any SR expert to tell anyone, you or
me or themselves, exactly why anything physically
occurs at all! What is done, when an SR expert
'explains' the paradox of the twins, is this:
They are good with their math. And by math, they
can give anyone the correct math answer. After they
give the correct math answer, then they can really
say almost anything they want to say, and if they can
say anything, then they can say that they gave an
answer. The proof that they gave an answer is the
correct math answer that they gave you.
This is all that is done. They often find a
different way, at times, to provide the correct math
answer, and they often use the same physical
explanations, but they never really have an answer
that really answers the problem. It is all smoke and
mirrors all the way. They love their geometry, and
will often show lines and angles. And they will say
that these lines and angles are physical
explanations. But their geometry is only math, and
is only showing their math answers, and does not
really address the physical explanation as to what
actually happens at all. They lie to themselves over
what is math and what is really physical.
Also, as was done in this reference (before I
stopped reading it), they made fun out of the
previous SR answers that had been given (as anyone
could do, because there really are no answers in SR),
before they begin their own answers, not realizing
that their own answers will be just as laughed at as
the answers they were making fun over.
As an example, let us take the answer they gave
you in the above, where you end up with your
question: At what point does the traveller 'leave
the earth's frame of reference?' Physically, it is
impossible to leave any SR frame. All SR frames are
all in the exact same reality, and no one ever leaves
any frame at all. Every object of reality exists in
every SR frame that exists, moving in that frame or
not. These words being used by this SR expert are
only words, with no definitions given or explained.
Many of these words that are spoken by SR experts are
habits, words they have said so many times that we do
not even pay them any attention. But every SR
problem can be worked out in any frame. And any
'change in frame' is merely a decision made by the
one presenting the problem. No change in frame can
change any result, or any action, as far as the
physical results and acts are involved. A change in
frame only changes the values of the position and
time coordinates, they can never change the physical
state of the objects involved.
When it was said that, 'The traveler's actions
define the events,' then you know that this is silly
and unscientific, if by this they meant to infer that
there is only frame in which the events could be
properly defined or calculated or understood. And
did they say: 'It is also an asymmetry that the
traveler and the homebody agree with the reading on
the traveler's clock at each event, but not vice
versa'? If they are trying to say that something
measured or observed in one frame is not exactly seen
in another frame (the words, 'not vice versa'), then they
are really crazy. They are not experts in anything
if they believe things such as this!
In LET it can be as simple as this: The stay at
home twin moves through the ether in a straight line,
the twin who goes out and returns moves though the
ether in a none straight line. A straight line is
always the shortest distance between two points.
This means that the twin who does not travel a
straight line had to have an absolute faster motion
in one or more legs of his trip, and will therefore
end up being the youngest.
This physical answer, which requires no math
(which makes it a physical answer), shows that there
is no paradox in this problem. This can be true in
every problem given in LET. But SR cannot address an
ether, it cannot address absolute motion, it can not
answer the twin paradox in any specific physical way.
Only LET has the means of addressing what really
physically happens so that the twin paradox can be
understood on the physical level.
Thanks for reading.
